The wood is shiny, straight grain, medium structure, but uneven. The material color is light yellow to yellowish brown. The difference between heart and sapwood is slightly or less obvious. It is easy to process such as sawing and planing, and the planing surface is smooth. Poor corrosion resistance. Air-dried wood density is about 0.639g/cm3; shrinkage coefficient: radial 0.191%, chord direction 0.333%; medium strength: along the grain compressive strength about 39.4MPa, static bending strength about 87.6MPa, bending elastic modulus 10GPa, along-grain tensile strength 91.6MPa, impact toughness a布特9.48 j / cm2;硬度: end face 51.8MPa, diameter face 41.6MPa, string face 45.1MPa. It is suitable for furniture and interior decoration, and can be used as sleepers, pit wood, bridges and other components, as well as wooden piles, carriages, ships, etc. It is also suitable for the production of plywood.
